O recomendador de ativar alta disponibilidade do Cloud SQL gera recomendações proativamente para ajudar a trazer suas instâncias importantes no SLA ao fornecer redundância de dados. Isso pode ser útil durante uma interrupção temporária de zona ou quando uma instância fica sem memória.
Nesta página, descrevemos o recomendador de ativar alta disponibilidade do Cloud SQL, como ele funciona e como usá-lo.
Como funciona
O recomendador de ativar alta disponibilidade do Cloud SQL analisa os metadados da instância. Se a instância estiver configurada de maneira semelhante a instâncias que aceitam cargas de trabalho importantes, mas não tenham alta disponibilidade ativada, o Cloud SQL recomendará que você ative a alta disponibilidade do SLA de disponibilidade de 99,95% ou migre para o Cloud SQL edição Enterprise Plus com alta disponibilidade do SLA de disponibilidade de 99,99%.
Preços
O recomendador de ativar alta disponibilidade do Cloud SQL está disponível sem custo financeiro para todos os clientes do Google Cloud .
Para mais informações, consulte Preços do recomendador.

Na tabela a seguir, listamos o insight e a recomendação gerados pelo recomendador de ativar alta disponibilidade do Cloud SQL. Os subtipos são visíveis na gcloud CLI e nos resultados da API.
Insight
Recomendação
Essa instância não está altamente disponível, mesmo configurada de maneira semelhante a instâncias que aceitam cargas de trabalho importantes. Instâncias de zona única são mais suscetíveis a inatividade.
Subtipo: CRITICAL_INSTANCE_HIGH_AVAILABILITY_NOT_ENABLED
Ative a alta disponibilidade do SLA de disponibilidade de 99,95% ou migre para o Cloud SQL edição Enterprise Plus, com alta disponibilidade do SLA de disponibilidade ainda maior de 99,99%. Ativar a alta disponibilidade tornará sua instância multizonal, o que replica os dados em uma região para proteger contra falhas temporárias de zona, limitar a inatividade e melhorar o tempo de recuperação.
Subtipo: ENABLE_HIGH_AVAILABILITY

This might\nbe helpful during a zonal outage or when an instance runs out of memory.\n\nThis page describes the Cloud SQL enable-high-availability recommender, how this\nrecommender works, and how to use it.\n\nHow it works\n------------\n\nThe Cloud SQL enable-high-availability recommender analyzes the instance metadata.

For more information, see\n [Enable and disable high availability](/sql/docs/postgres/configure-ha#console_1).\n\n | **Caution:** Once you start the high availability configuration on an instance, you can't stop it. This operation restarts the instance and can lead to an increase in cost and a brief downtime. It typically takes only a few minutes for the configuration and the restart operation to complete. However, if the instance has a large disk or load, then it might take up to an hour.\n - Migrate to the Cloud SQL Enterprise Plus edition.
